An object of mass `m` slides down a hill of arbitrary shape and after travelling a certain horizontal path stops because of friction. The total vertical height descended is `h`. The friction coefficient is different for different segments for the entire path but is independent of the velocity and direction of motion. The work that a tangerial force must perform to return the object to its initial position along the same path is
